Background
A jury convicted Zshavon M. Dotson of first-degree premeditated murder for fatally shooting his friend Ronald Marks and of aggravated battery for injuring Marks’ mother, Carolyn Marks. Dotson testified that Ronald and Carolyn attempted to rob him at gunpoint and that he wrested a rifle from Ronald before shooting him in self-defense. Carolyn testified that Dotson seized the rifle during an argument, overpowered Ronald, and shot him. The Kansas Supreme Court affirmed the convictions in 2024.
In 2025, Dotson sought postconviction DNA testing under K.S.A. 21-2512. Although his pro se motion listed several items, his request focused on biological material associated with the rifle. After appointing counsel and holding an evidentiary hearing, the district court denied testing, finding among other things that Dotson had not shown the requested testing would produce exculpatory evidence. Dotson appealed, arguing that the district court improperly limited his request to the rifle barrel instead of considering swabs reportedly taken from the firearm’s trigger, pistol, and grip.
The Court’s Holding
The Kansas Supreme Court affirmed. It concluded that, despite some lack of clarity in the district court’s order, the lower court had considered testing of the swabs from the rifle and had not restricted its analysis solely to the barrel. More importantly, Dotson failed to make a plausible showing that testing those swabs could produce noncumulative, exculpatory evidence as required by K.S.A. 21-2512(c).
Evidence that Ronald’s DNA was on the trigger would show only that he had touched the trigger of his own rifle, an undisputed fact that would not prove a disputed material issue. Evidence of Carolyn’s DNA on the rifle likewise would not support Dotson’s innocence theory because Dotson had never claimed that Carolyn touched that rifle; his defense was that she threatened him with a different firearm. Because the proposed results would not tend to establish a disputed material fact, the district court did not err by denying DNA testing.
Key Takeaways
- A Kansas court need not order postconviction DNA testing unless the petitioner plausibly shows that testing may produce noncumulative, exculpatory evidence.
- DNA showing that a victim touched the victim’s own firearm is not exculpatory when that contact is undisputed.
- A possible DNA result does not support testing when it would not prove a fact material to the petitioner’s asserted theory of innocence.
Why It Matters
The decision emphasizes that K.S.A. 21-2512 does not authorize testing merely because biological material may exist or because a petitioner can imagine possible results. The requested testing must be capable of producing evidence that bears on a genuinely disputed and material fact supporting wrongful conviction or sentencing.
For postconviction practitioners, the opinion underscores the need to connect each proposed DNA result to the trial record and to explain specifically how that result would advance the petitioner’s innocence theory.
